Subject [jira] Resolved: (HADOOP-204) Need to tweak a few things in the metrics package to support the Simon plugin
Date Fri, 12 May 2006 21:16:09 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-204?page=all ]
     
Doug Cutting resolved HADOOP-204:
---------------------------------

    Resolution: Fixed

I just committed this.  I changed the name of the file generated by the "metrics.jar" task
to be hadoop-metrics-X.X.jar, where X.X is the hadoop version.  Should this artifact be included
with Hadoop releases?  If so then we should make sure that it is bundled into the .tar.gz
file built by the "tar" target.  Or do we always expect its consumers to build it themselves?

> (1) added an extra metrics.jar target to the build.xml so that I can build a stand-alone
library containing only the
> metrics package and its subpackages.
> (2) added serialversionUIDs to a bunch of classes to make Eclipse happy
> (3) made AbstractMetricsContext.createRecord final, and added a protected newRecord that
subclasses can use
> to customize record creation without breaking the parent class.
> (4) minor fix to how errors in callbacks are handled
> (5) constructor in MetricsRecordImpl made protected rather than package private so that
it can be subclassed
> (6) extended Util.parse(String serverSpecs, int defaultPort) to handle the case of a
null serverSpecs by defaulting to localhost
